Matrix metalloproteinase-2 (MMP-2) is involved in several physiological mechanisms, including wound healing and tumor progression. We show that MMP-2 directly stimulates dendritic cells (DCs) to both up-regulate OX40L on the cell surface and secrete inflammatory cytokines. The mechanism underlying DC activation includes physical association with Toll-like receptor-2 (TLR2), leading to NF-κB activation, OX40L up-regulation on DCs and ensuing TH2 differentiation. Significantly, MMP-2 polarizes T cells towards type-2 responses in vivo, in a TLR2-dependent manner. MMP-2-dependent type-2 polarization may represent a key immune regulatory mechanism to protect against a broad array of disorders, such as inflammatory, infectious and autoimmune diseases, which can be hijacked by tumors to evade immunity.
